Trouble Shooting

[Trouble Shooting] If cracks occurs on objects printed with ABS material, ...



Because of the nature of the material, ABS has strong contraction which may cause cracks due to shrinkage during printing. 

Especially, depending on the low temperature in the winter and the shape of the output, cracks may occur. 


1) Seal Printer.

   - Since ABS adhesion increases as the temperature around the print area increases, it is possible to improve the adhesion by closing all the windows on the front and top of the machine and printing it while closed tightly.


2) Increase Bed Temperature.

   - By raising the bed temperature it is possible to reduce the occurrence of cracks. If the crack occurs severely, it is recommended that you set the bed temperature to 100 ~ 110 ℃. However, in this case, the time to print and power consumption may increase, so it is recommended to apply it only when necessary. 

   - Adjust the Bed Temperature in the Basic tab of Profile Settings in Advanced Mode.


3) Increase Flow Compensation.

   - When the Flow compensation value is changed to 110% from the default value (105%), the occurrence of cracks can be alleviated. However, please do not apply this setting for prints requiring sophisticated dimensions such as gears and joints.

   - Adjust flow compensation in the Basic tab of Profile Settings in Advanced Mode


4) Wait after printing finishes.

   - After the ABS print is completed, if the printed object is quickly removed from the printer, a sudden temperature change may cause cracks. It is recommended that you take out the printed object after having sufficient standby time inside the printer so that when the print is completed, the ABS print can be cooled down gradually.

[Trouble Shooting] When the quality of the bottom of the printed object is poor...


If the bottom surface is uneven, the quality of the object bottom can be poor.

In this case, you can improve the quality by reducing the air gap in the slicer application.


- Open Sindoh 3DWOX Desktop Slicer.

- Click 'Mode' from the top menus and select 'Advanced Mode'

- Go to Settings and click the Bed Adhesion tab at the bottom.​

- Adjust the First Layer Airgap field of the Bed Adhesion tab​. (e.g. 0.25 → 0.20) 




If problem, please contact us via 3D Website > Contact us. 

[Trouble Shooting] Measures for the incompletely filled surface

1. Incompletely filled surface on the model

In some models, such as the one shown on the left, the surface of the model may not be completely filled, causing incompletely filled surface and poor surface quality.

2. Troubleshooting

1) Change of Flow Compensation(%)

Increasing the value of Flow Compensation to 120% will increase the amount of the filament excreted from the nozzle, solving the incompletely filled surface problem. (Default rate at 100%)

However, please be advised that high extrusion rate, which increases filament excretion, may cause problems in filament feeding, affecting the dimensional accuracy of the output.

2) Change of Infill Density

If the change of Flow Compensation does not solve the problem, changing the value of Infill Density will be helpful.

By increasing the amount of the filling inside the model, the incompletely filled surface problem can be solved.

              Infill Density of 15%                                    Infill Density of 30%

However, increasing the Infill Density can increase the amount of filament consumption more than necessary and also the total printing time. 

[Trouble Shooting] The adhesion issue of the exterior of the print bed


1. Decrease of bed exterior adhesion

In the case of the edge of the bed, since it is the part where the user's hand often touches,

the adhesion of the output may be decreased due to contamination of the oil.

2. Troubleshooting

- Cleaning the bed surface

Rub with the Scraper either the edge of the bed or the place where the warping occurs. 

Or rub it 4~5 times with sandpaper. (600 ~ 800 Grit) 

And clean it with alcohol so as not to leave foreign matter. 


[Trouble Shooting] How to remove broken filament inside of the machine

1. When the filament is broken inside of the machine

If the error such as Notification number 412 ~ 417 continues to occur or you can see the filament being broken in the tube, please follow the troubleshooting guide below.

2. How to troubleshoot the problem

1) Remove the cartridge first. Go to and select mode.

ⓐ Select the nozzle side where the filament is broken. 

ⓑ Select <100> to move the filament 100 mm.

ⓒ Select the unloading direction and keep pressing it until you see the filament coming out of the machine. 

ⓓ Once you can see the filament moving out of the printer through extruder, remove the broken filament by gently pulling it.


2) If the problem continues even after following the instructions above, refer to the section 'Before using the machine' - '6. Instructions for Use'  of the user manual and disassemble the extruder to remove the filament from the extruder.

3) If there is a filament residue in the nozzle, follow the instructions below.

① Remove the white snap wring from the nozzle.

② Pull out the tube upward as you push down the tube hold.

③ Remove the filament out of the tube.


[Trouble Shooting] Crack of ABS printout

1. Crack of ABS printout

Due to the material properties, ABS has a strong tendency to shrink and may create cracks during printing.

Cracks may occur depending on the low temperature in winter and the shape of the object.



2. Troubleshooting


- Close the Doors

Since the occurrence of cracks in ABS printing can be reduced in higher temperature environment, closing all doors on the printer will help reducing the crack. 


- Increase Bed Temperature

Raising the temperature of the bed can reduce the occurrence of cracks. If occurrence is severe, it is recommended to set the bed temperature to 100 - 110 ℃. However, please note that in this case, the warm up time may become longer than the standard temperature setting and that power consumption may increase so we recommend to do this only when it is needed.


- Increase Flow Compensation

The occurrence of cracks can be reduced  by changing the standard extrusion value(105%) to 110%. However, do not apply this setting for prints that require precise dimensions, such as gears or joints.


- Wait after the print is completed

It is recommended that you take enough time before taking the ABS printed object out so that it can be gradually cooled in the printer. 

[Trouble Shooting] Oozing(Stringing) Problem


-Oozing(Stringing) is printing quality problem that string shape occurred on printout additionally.

This problem occur because filament oozing out while the nozzle move to the new position.





-Manual Removal

-Remove the string by hand or nipper like tool.

Usually, string is attached to the printout weakly and the attached cross section is narrow. 

So It can be removed easily.


- Lower the Nozzle Temperature

If the nozzle temperature is higher, filament viscosity inside nozzle can be smaller and filament can ooze out easier. Therefore, you can resolve the stringing problem by lowering the nozzle temperature.

Please be careful not to lower the nozzle temperature excessively. 

If you lower the nozzle temperature overly, filament cannot be melted enough so filament cannot be transferred smoothly. 


- Increase the Nozzle Travel Speed

If the nozzle travel speed increase, time of filament ooze from nozzle decrease while the nozzle moving between printouts.

Please be careful not to increase the nozzle travel speed excessively. 

If you increase the nozzle travel speed overly, motor noise and print quality problem can be occurred.


- Increase Retraction Speed & Length

Increasing the retraction speed and length is the most effective way to reduce the oozing(stringing) problem.

Please be careful not to increase the retraction speed and length excessively.

If you increase the retraction speed and length overly, filament transfer problem and stepping motor problem (out-of-step) can be occurred.  

[Trouble Shooting] The power is on but the LCD does not work.

[Trouble Shooting] Model Warping Improvement
Usual warping occurs when the excreted Filament starts to cool down.
The newest Filament that has been excreted on the highest layer has a higher chance of warp, which is the reason why the corners of the 3D models warp.
ABS Material has more tendency to warp than the PLA material.

Warping Improvement Instructions:

1. Operate 3DWOX at a fairly warm temperature (61 ~ 84)
  - Cold weathers can cause warp in the printed models.

2. Close all the doors while printing.
  - Opening top and front doors can affect the printed model

3. In cases where the shape of the 3D Model has a Countergradient or Bridge shaped bottom, please turn off the fan.
  - In order to change the Fan settings, change the mode to advanced mode.
  - Go to Settings - Advanced (2) - Cool - Minimum/Maximum Fan Speed and change the values.
  - Default value for PLA is 50% and ABS is 3%

4. Change the Infill rate of the model.
  1) Change to Advanced Mode(Mode - Advanced Mode)
  2) Change the Infill Rate (Settings - Basic - Fill - Fill Density)
  - Default value for PLA is 15% and ABS is 10%

5. Go through the manual Leveling.
  - Please refer to the [FAQs] - [Trouble Shooting] - [Manual Bed Leveling Method] tab.

6. For large sized models with large bottom surface, please print with PLA. 
  - ABS has a tendency to contract easily.

7. Please print the model in the middle of the bed.
  - Corners of the bed sheet (especially close to the front door) are easily affected by the outside temperature, causing warp.

8. Use as least time as possible for pausing.
  - During the pause, the inner temperature of the 3DWOX decreases, which can affect the warping of the 3D model.


9. Clean the bed surface.

  1) Slightly rub the bed surface with sandpaper.

  2) Wipe bed surface off with alcohol(ethanol).

  - Bed surface can be contaminated by oil on hand.


10. Increase the bed temperature. (Only for ABS ) 

  - Increase the bed temperature from 90℃(default) to 110℃. ​ 

[Trouble Shooting] Manual Bed Leveling Method
** Before the execution, please go through "Auto Bed Leveling".
(Refer to the following link:, "BedLeveling")

1. Get a business card (or a hard surfaced paper)
2. On the printer display, go to Setting - Z offset
  - Move The nozzle and the bed will move around and eventually the nozzle will position on the middle of the bed

3. Pull the bed until the Sindoh logo is covered

4. Push the business card in between the nozzle and the bed and move it around. If you feel a little bit of scratching the bed level is complete.

* Caution. There is a spring system under the bed. If you press the bed down while moving the business card around, the bed will move downward, causing an incorrect leveling of the bed.
  - If you cant move or cant fit the business card in between the nozzle and the bed = Increase the Z offset value and press move
  - If you cant feel any scratching on the business card = Decrease the Z offset value and press move
  - On the appropriate Z offset value, press save

5. Push the bed back and manually move the nozzle to the left end.
Same way as Step 4, push the business card in between the nozzle and the bed and calibrate until the appropriate height.

During calibration, do not use the Z offset menu, but instead, turn the knob.
- If you cant move or cant fit the business card in between the nozzle and the bed = Turn the knob clockwise 
- If you cant feel any scratching on the business card = Turn the knob counterclockwise

* Rotating the knob by one revolution changes the height by 0.8mm.
Rotating the knob by one edge changes the height by 0.1mm
* Please rotate ONLY the Left knob!

6. After the left side calibration is complete, move the nozzle to the right side.
Repeat step 5.

7. Usual calibration ends after step 6.
Users can print a small object to see whether the bed leveling calibration is appropriate enough for printing. 

1)Bottom surface is wiggly -> Decreases Z Offset.

2)Bottom surface is pushed -> Increase Z Offset.​
* Example of printed work with Z offset of 1mm higher than the appropriate value

3)Appropriate Z Offset.
* Example of printed work with Z offset 0.5mm less than the appropriate value

Go through Setting - Next - Test Print - Line Test (Approximately 25 min)

* The bed leveling becomes very sensitive when outputs are printed without a raft.
Unless under certain circumstance, please use the Raft On option when printing.
* If Advanced Mode, Check the Settings.
* Advanced Mode : Settings - Basic - Support - Bed Adhesion Type - Raft

[3DWOX Desktop S/W] Is there any limit for the sliceable file size?

Currently, 3DWOX Desktop is 32 bit SW, so it can use 4G memory at maximum. 

If the stl file is over 600MB, it can require more memory size over this limitation. 

In this case, you can resolve the problem by decreasing the stl file size.

You can decrease the file size by decreasing the triangle size when you save the file in CAD program.

[3DWOX Desktop S/W] Tips for placing the model
- Output quality could vary depending on how user positions a model on the bed.
*Place the model in a position where the usage of support is minimized.

*​If the usage of support is necessary, place the model while considering the fact that parts touching the support would be low in printing quality.

Place the important part of the model facing up              Parts of the model attached to the support
so its surface would be more precisely printed.​               are low in printing quality
   ->after slicing     

*​If the part has a hole or boss that needs to be precisely printed, it is better to place the part standing up so it wouldn’t need a support.

A hole that needs to be precisely printed                  A hole that needs to be precisely printed

1)Since this boss needs the support, it would be less precisely printed.
2)If this part needs to be precisely printed more than the other part, make sure to place this part facing up so it wouldn't need a support.

[3DWOX Desktop S/W] Tips for using the Support feature
- The less the usage of support, the better the printing quality.
*If the model’s angle is within 60 degrees from the perpendicular, it can be printed stably with out the usage of support.
These parts (within 60 degrees) are stable                    Default settings are set to only create the 
without the usage of support.​                                        support for parts of the output with larger than 60 degrees.

Change the value in the box If you want to set a support for parts with angle less than 60 degrees.

*Even if the angle is large, it is still possible to print the model without the support if the model is short in length and has pillars on each side.

You can stably print the model of length up to 40 mm if there are supports on the each side of model.


[3DWOX Desktop S/W] What are the differences between 'grid' and 'line' for infill pattern?
1) "Grid" infill is created in the shape of a grid.
(layer 120)

(layer 121)

2) "Line" infill is created in the shape of a line. The directions vary depending on the layer.
Therefore, it may look like a grid from the 3DWOX desktop.
(layer 120)

(layer 121)
[3DWOX Desktop S/W] Although the 'Line Count' is set as 1 under 'Skirt', a skirt is not being printed.
How can it be printed? 

"Skirt" is a paramater that operates only when "Bed Adhesion Type" is set as "None".


Therefore, you can print the skirt (The Green line shown below) if you set the "Bed Adhesion Type" as "None".


[3DWOX Desktop S/W]Shape Error Correction

​-Print Only Follow Mesh Surface-


This option is used when a user only prints the surface of model. Since this option only prints the surface, it prints the model’s outer wall without infill and upper/bottom surfaces. When printing the outer wall, this option prints in minimum thickness about nozzle size.


This option is used when a model is only composed of surfaces and has empty internal space as shown in the pictures below. In case of models with no upper/bottom surfaces and has thin walls, it would be hard for normal slicer settings to discern the inside and outside. Therefore, it will create the g code as it in fills the inside of the model. In such a case, this option can be used to only print the outer wall of the model without any infill.




[3D model] Its internal space is empty and         [When the option is selected] Printing the 

has opened entrance.                                               outer wall without infill, upper/bottom surfaces. 


[When the option is unselected] If this option

is unselected, it would be sliced as an infilled

model as it is an opened type.


Also when the thickness of the outer wall is about 0.4 mm thin, it would be not possible to print it under regular settings. But when this option is activated, it would be possible to print the outer wall.



[3D model] When the thickness is 0.4mm,           [When the option is selected] Can print the

which is a size of the nozzle diameter                  outer wall is thin if this function is enabled


[When the option is unselected] Does not 

create the outer wall due to the thickness 

(too thin) because the creation of outer wall,

inner wall, and infill are simultaneously executed.


However, we do not recommend this function when slicing a model that requires the solidity, because there is no infill and it prints with the least thickness, which results in printing the model with little solidity.


​-Combination Mode A-


When this option is selected, it slices a combination of two or more different models with overlapped part or only one model with overlapped surfaces. As shown in pictures below, two overlapped models share the inside and create the g-code when they are sliced.


When surfaces of the model meet, they create a shared internal space and infill. As shown in pictures above, 2 or more models could be overlapped. Also this option could be used for a single model. For v., this option has been activated as default.


​-Combination Mode B-


If you select this option and slice the model above, it starts slicing by integrating as the picture below and filling the internal empty space at the same time. When you need to print just the exterior of the model, this option enables you to slice in case the slicing cannot be initiated due to the entanglement or the overlap of the model.



On the same model as above, it creates the G-Code by extracting the exterior and filling the internal space.


​-Close Open Faces-​ 


This option is used to resolve an issue when slicing cannot be initiated due to a crack or a hole which are created when surfaces are not properly connected to each other. When you upload a model and slice, you may find that a part of the model disappears from time to time. Such phenomenon occurs due to invisible small cracks or holes, although there seems to be no problem externally. When designing the model, the model with defects may be created under a number of circumstances. For example, they can be created when they have been inconsistently scanned or when they have been improperly attached together.



The picture on the left above is a STL model of a rabbit and the picture on the right above is when the STL model is sliced. There seems to be no problem when uploading a model. However, if you initiate the slicing process, you can find that the part between the legs and the body disappears. A defect of the associated part’s data can be suspected.



It is difficult to find the models with defect on the current slicing program. You must check on the program that professionally deals with the model. The picture on the left is what appears when the same model is loaded on the program called “Meshmixer” which has been developed by Autodesk. This program simply analyzes the surface of the model and displays it on the screen. On the left picture, you can find the blue lines on the body and the legs of the rabbit. Namely, the model does not consist of a single model. It is a model that is created by attaching the legs and the body. The blue line is created where the legs and the body are attached. In case the size of a crack surpasses a certain size, the slicer cannot create a path of a nozzle and delete it on the screen. This feature attaches these cracks so that the model can be sliced.



When you enable this option and re-slice, you can find that the path, which has been fixed to a certain extent, has been created.

However, this feature can fix the defects such as small cracks only to a certain extent. The user may not be satisfied with the result. In the cases when the size of cracks and holes are too big, you need a program of which the user can manually modify the model.


​-Extensive Stitching-


The concept of this option is similar to ‘Close Open Faces’ option above but it is used in a case in which the gaps between surfaces of the model are bigger. When ‘Close Open Faces’ option is selected, slicer makes decision to fill in the gaps or little holes of the model, but when extensive stitching option is selected, slicer makes decision to connect a surface to another closest surface when there is two or more open surfaces in between the surfaces to be connected. The user may not be satisfied with the result so the usage is limited to the certain extent.? 

[3DWOX Desktop S/W] A 'gap' is observed on the upper part of the printed object. What measure should be taken?
A gap can form in case the upper surface area of the printed object is wide and multiple movements take place inside the model, leading to filament loss.
You may prevent the "gap" on the surface of the upper part of the printed object from forming by modifying the settings on "3DWOX desktop." However, be mindful of additional problems.
You may modify the settings by clicking "settings" after switching the mode to "Advanced Mode." The settings below may change depending on the printing or device conditions.
Basic > Filament > Flow Compensation : 130% 
Advanced(1) > Speed > Travel Speed : 180mm/sec
Advanced(1) > Speed > Top/Bottom Speed : 20mm/sec
Advanced(2) > Retraction > Retraction Combing : No Skin

Printing quality may decrease when printing under the modified settings. Therefore, please reset the settings and print.(Setting > Reset Profile)


[3DWOX Desktop S/W] Skin Outline
Skin Outline reinforces the outline of skin area so as to help in building the top and infill together on 1 layer.

For example of Venus shape, the outline is reinforced between the infill and top of it. For FDM, there can be a gap between the boundary of leg line and top plane of Venus shape. With the skin outline, the gap of boundary line can be improved. The following image will help understanding.

[Before applying skin outline]
The outline is not reinforced between the infill and top.​

[After applying skin outline]
The outline is reinforced between the infill and top.


[Operation/Maintenance] How do I clean the printer?
For the cleaning case, the printer will notify you on when to clean the case, follow instructions. For the nozzle in times of changing material or changing color of filament, under settings initiate nozzle cleaning.


[Operation/Maintenance] What is the purpose of bed lock and why and when do I want to lock and unlock?
The purpose of the bed lock is to easily reinstall the bed sheet on to the bed. When you are reinstalling the bed sheet, if the bed lock button is enabled, it will hold the bed so that the bed won't be pushed back when you slide the bed sheet on to the bed.

Aside from this bed lock function, when the print is completed, the bed is automatically lowered to the bottom and the long screw that is on the bottom of the bed holds the bed which works the same as the bed lock function so you don't have to worry about pressing the bed lock button when the print is completed. 

You will be using the bed lock button when you have to reinstall the bed sheet after you cancel the print or in situations where the bed is not at the bottom of the printer.


[Operation/Maintenance] Can the USB stick be removed during printing, and should the bed be releveled between each print?

You may remove the USB stick when the X-sign (Refer to the picture below) disappears on the screen. The bigger the size, the longer it will take for the X-sign to disappear.


[Recognizing the USB]                                   [USB may be removed]


There is no need to re-level the bed in between prints unless the device is substantially impacted.We recommend that you level the bed every other week if you print once or twice a day. However, there is no need to level the bed as long as the object is properly attached to the bed when printed.

[Operation/Maintenance] Has anyone experimented with faster print speeds? The default seems to be 40 mm/s, do you think the printer would work well at higher speed?
The maximum speed is 200mm/s. We recommend that you print at a speed of 100mm/s or under. However, printing at a speed of 40mm/s or lower is recommended due to a noise.
